The Azden SGM-250P is a professional shotgun microphone
designed for broadcast, news gathering and film making
applications. The SGM-250P boasts all the same features and
sound quality performance as the SGM-250 model, except
that the SGM-250P operates on phantom power exclusively
(no battery option).
Power
Phantom power is a DC voltage supplied through a balanced
microphone cable and used to power the electronics of the
connected microphone. Most professional cameras, mixers
and audio interfaces with microphone XLR pre amps have the
ability to supply phantom power. If the equipment you use
does not, you will have to utilize a separate external phantom
power supply.
Most commonly, phantom power is supplied at 48V. This is
the optimum voltage for the SGM-250P. It is possible that your
connecting equipment supplies a different voltage. The
SGM-250P is rated to work on a voltage between 11 and 50V,
however, performance will degrade with lower voltages and
damage to the electronics could result when using voltages in
excess of this range. It is recommended that you consult the
manuals of any equipment you intend to use with the
microphone beforehand. Please note that the warranty does
not cover damage caused by using phantom power beyond
what the microphone is rated for.
Low-Cut Filter
The SGM-250P is equipped with a switchable low-cut filter.
Set at 160Hz with a 3dB/octave roll off, Azden engineers
specifically designed the low-cut to be noticeably more
effective at reducing low frequency ambient noise (caused by
rumble, wind, HVAC systems, etc.) with a smoother and more
natural sounding bass attenuation. This makes the low-cut
filter also great for compensating for the natural low frequency
boost that occurs when using the microphone up close
(proximity effect).
The low-cut filter switch has two positions:
Flat position (low-cut filter off)
Low-cut filter on
* Do not operate the low-cut switch while recording as doing so may cause noise.
